· In0.2Co4Sb12

In0.2Co4Sb12 is a filled skutterudite compound—an intermetallic material where indium atoms are partially filled into the cage-like crystal structure of cobalt antimonide. This is a research-phase thermoelectric material being developed for solid-state heat-to-electricity conversion applications. The filled skutterudite family is notable for its ability to decouple electrical and thermal transport properties better than conventional thermoelectrics, making it attractive where traditional materials reach performance limits.

Regulatory Screening

Environmental

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
